Hi Guys

A friend of mine has a 2013 M135i Manual and is looking for more power.
I told him to start with JB4 and maybe a DP and AFE Intake later on.

Is there anyone on the forum that does installation of JB4?

Hes Based in Durban

Also I did some research and found that the JB4 for a 335i N55 and the M135i N55 is not the same? So not sure which one to tell my friend to order.

BTW he just likes driving cars, doesn't even own many tools lol , So he wants someone who knows what they doing to install it.


Thanks

Thanks Twins

Will tell him to do that.

Its a 2013 think it will be Pneumatic. 2014 Onwards came with EWG AFAIK

Any other good Piggyback/ PNP you suggest looking into Twinz?

The Jb is the preferred piggyback tune amongst most.

We also promote the Racechip but have had zero feedback on the M135.

What is the difference between pneumatic and ewg?


Sent from my  iPhone

Pneumatic - wastegate controlled with vacuum
Ewg - wastegate controlled electronically

Might be under correction.
